I forgot to say 2 things earlier.
The box we use every year is a cardboard gift box which I was given filled with various bits when DD was very small. It is somewhat Christmas patterned, and most of the year it holds our festive collection of DVDs and Mr Men sized books. They come out in early December, and it gets repurposed on Christmas Eve to hold "CEH" contents.
The second point is that DD has always known it was me who did the hamper. It was never a special Elf delivery. And it has never featured in social media or photos, ever. I have talked about it on here, but it is something that we do in our house when it is just us 3. And it is for the entire house, not just DD.
It is something that suits us, to signal the move towards bed for DD (ASD/ADHD so sleep has always been an issue and routine is terribly important).
But it is also involving things we would have in winter anyway.
It is not essential.
Do not do anything in real life that is not within your budget or something that suits you and your family circumstances.
Christmas is what you make it. Lots of our Christmas is playing music on the radio and enjoying the slower pace of life for a few days. Not consumerism.
There are lots of things that can make things "magic", some cost a lot, some are very cheap or free.
But also don't get so caught up in the need for "magic" that you get totally stressed and the DCs remember that instead - just aim for an enjoyable time, with some fun, and everyone able to enjoy it (including the "magic-maker").
